Objective To explore the relationship between self- management and DOSE index for patients with chronic obstructive pulmonary disease (COPD). Methods The convenient sampling and Pearson correlation analysis was used in the study,a total of 81 patients was investigated with Self- Management Scale (SMS) for COPD patients and DOSE index. Results The relationship of symptom management and DOSE index for COPD patients was a positive correlation (r=0.259, P<0.05);with self- efficacy was a negative correlation(r=-0.288, P<0.05).But self- management, daily life management, emotion management and information management with DOSE index were no correlation (P>0.05). Conclusions Through health education, nurses should strengthen to effectively help patients manage symptoms, enhance self- efficacy, improve the patients′quality of life.

Alzheimers disease (AD) is a progressively and retrogressively neurodegenerative disorder of central nervous system severely threatening the aged. The studies of animal models, which share the very similar neuropathological characteristics with human, provide tools for the understanding of the etiology, mechanisms and medicine screening of AD. The distribution and chemical composition of amyloid-beta (A- beta) peptide -positive deposits were investigated in various non-human primate models. Various proportions of A- beta deposits contained cholinesterase activities, apolipoprotein E(ApoE) and alpha1-antichymotrypsin immunoreactivity. Alterations in the basal forebrain cholinergic system have been widely studied, but the magnitude of decline and relationship to cognitive impairment are still a matter of debate. This article also includes the latest research of the changing on tau, subtle structural alterations in axons, and neurofibrillary tangles (NFT) in the brain tissues of the non-human primate models.

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by memory loss and cognitive decline. The pathological eatures of Alzheimer's disease are abnormal deposition of amyloid beta-peptides (Aβ), neurofibrillary tangles, cholinergic deficits, and loss of synaptic processes and dendritic spines. Senescence accelerated mouse prone 8 exhibits age-related deficits of learning and memory from an early age, tau protein phosphorylation, neurotransmitter changes, synaptic structure and function disorders, circadian rhythm disorders,as well as gene expression and many other characteristic changes, which are consistent with Alzheimer's disease pathological changes，and can be used as an ideal animal model for Alzheimer's disease prevention drugs development.

ObjectiveTo observe the easing pain effect of being used Guishen Pain-Killer, a Chinese medicine, for improving the anaesthesia project which was used in using micro-wave heating among tissue to treat hemorrhoid.MethodsOn the basic of the original anaesthesia project, patients drunk the Chinese medicine Guishen Pain-Killer 50ml which was heated to 40℃ by microwave stove for pre-anaesthesia drug 10 minutes before the operation. The effect of adding drinking Guishen Pain-Killer and of merely using the original anaesthesia project were estimated with the McGill Questionnaire and stated the data with u test.ResultsThe pain estimation of those patients who drunk Guishen Pain-Killer before operation was (1.71±1.05) and (1.32±0.83), in operation and just after operation,while that of patients who didn't drink Guishen Pain-Killer before operation was (2.58±1.03) and (1.93±1.11),P<0.01.ConclusionGuishen Pain-Killer can be used as the pre-anaesthesia drug in micro-wave heating among tissue to treat hemorrhoids.

Objective: To evaluate the effect of pingyangmycin-albumin microspheres (PYM-AMS) on the modality of endothelial cells. Methods:In the in vitro study blood vessle endothelial cells of ECV 304 cell line were exposed to PYM-AMS(containing PYM at 150 ?g/ml),AMS and PYM(150 ?g/ml) for 24,48,72 and 96 h respectively. In the in vivo study,24 Japanese white rabbits were divided into 4 groups using randomized block design. PYM+9 g/L NaCl,PYM+soyabean oil, PYM-AMS+soyabean oil(PYM at 5 mg/ml) were injected into the central auricular arteries of the animals(0.26 ml/per ear), then these vessels were examined histologically 2, 7, 14, 21 days after injection respectively. The mophorlogy of the cells was observed by light microscope and electron microscope.Results:In vitro, a great part of cells were swollen and cell number decreased in PYM and PYM-AMS group. But there was no change in AMS group.In vivo, the endothelial cells had no significant changes in PYM+9 g/L NaCl group.In PYM+soyabean oil group, at the 2nd day, the endothelial cells were a little bit swollen. At the 7th day, some endothelial cells were dropped off. At the 21st day, a few of endothelial cells were proliferative. In PYM-AMS group, at the 2nd day, the endothelial cells were a little bit swollen and small vessels were embolized by PYM-AMS. At the 7th day, the endothelial cells were swollen. At the 14th day, the endothelial cells were proliferative and the wall of the central auricular artery had more layers. The lumen of the central artery became smaller, while the surface of PYM-AMS was absorbed. At the 21st day, the wall of the central auricular artery was proliferative and the artery became sclerostenosed. The PYM-AMS was obviously absorbed, while the wall of small vein was proliferative, too. Conclusion:PYM-AMS and PYM may injure blood vessel endothelial cells, the effect of PYM-AMS is more obvious than pingyangmycin.

Objective To evaluate the potential effect of HLF (Hawthorn leave flavonoids, w/w, 80% flavonoids) against thrombus formation, effect of HLF on hypoxia-treated human umbilical vein endothelial cell (HUVECs) was studied. Method The levels of cytotoxicity and NO upon HUVECs were studied by flow cytometry. Moreover, the level of calcium ion in HUVECs was examined through laser scanning confocal microscopy. Result Data from this study showed that HLF at concentrations of 5 μg/ml and 10 μg/ml decreased the cytotoxicity of hypoxia to HUVECs (P<0.05, P<0.01). The intracellular levels of NO and calcium ion were downregulated by HLF at concentrations of 5 μg/ml (P<0.01; P<0.01) and 10 μg/ml (vs control, P<0.01; P<0.01) too. Conclusion Results observed suggest that HLF protect HUVECs from hypoxia partly through its regulative effect on NO and calcium ion levels.

Objective To observe the effect ofmycophenolate mofetil combined with prednisone in treatment of old patients with refractory nephrotic syndrome.Methods From June 2009 to June 2010,67cases of old patients with refractory nephrotic syndrome were divided into two groups by random digits table,32 cases in control group were treated with cyclophosphamide combined with prednisone and 35 cases in observation group were treated with mycophenolate mofetil combined with predrisone.The clinical effect and the levels of urinary protein,serum creatinine and serum uric acid between two groups were compared.Results There was no significant difference in total effective rate between two groups [68.8％(22/32) vs.74.3％ (26/35)] (P ＞ 0.05 ).After treatment,the levels of urinary protein,serum creatinine and serum uric acid in two groups were decreased (P＜ 0.05 ),but there were no significant differences between two groups (P ＞ 0.05 ).The adverse reaction rate in observation group was significantly lower than that in control group (P ＜ 0.05).Conclusion Mycophenolate mofetil combined with prednisone in treatment of old patients with refractory nephrotic syndrome has good effect and low adverse reaction,and it can be applied in clinic.

As the important content of excellent quality nursing service, the performance appraisal of nursing staff was closely interrelated to their income distribution, professional title promotion and excellence choosing. Performance appraisal was the requisite part of nursing resource management. This study gave an overview about conception and development of nursing staff′s performance appraisal and summarize key performance indicator,balanced score card,SMART principle and 360 degrees performance appraisal, which was mainly used in domestic hospital. It suggested nursing manager should have complementary advantages of them and utilize foreign mature methods to explore and improve our countries performance appraisal of nursing staff and formulate the system which was in keeping with China′s national conditions.
